I have a few questions about how messages get redelivered. I'm using an
embedded broker (in tomcat). The version is 4.0 RC3.
1. How do you configure the redelivery delay for all queues. Right now i have
the configuration:
<destinationPolicy>
<policyMap>
<policyEntries>
<policyEntry queue="*">
<redeliveryPolicy initialRedeliveryDelay="10000"
useExponentialBackOff="true" backOffMultiplier="5" maximumRedeliveries="5" />
</policyEntry>
</policyEntries>
</policyMap>
</destinationPolicy>
But it seems to have no effect. The redelivery delay is still 1 second.
Should I specify ">" or "*.>" for all queues? I'm setting the XML file
location using the property brokerXmlConfig and calling the method
ActiveMQConnectionFactory.setProperties. Does this still work in 4.0? It
looks like this is how ActiveMQInitialContextFactory creates it's connections,
so i assume so.
2. The redelivery policy seems to take effect on calls to Session.recover and
Session.rollback. What happens to the unacknowledged messages if neither of
those methods get called? Will they ever get redelivered before the broker is
restarted?
3. It looks like the back off multiplier isn't taking effect. I printed out
some debug data and here is what i got:
Redeliverying message after delay 1000
Rollback counter: 5
Init delay: 1000
back off multi: 5
After the 5th rollback, the delay is still the same as the initial delay
(1000). I'm still debugging this, so I'll let you know if I find out anything.
Thanks for any help you can provide.
